正则表达式。 在php中查找函数名称

Question

I'd like to write regular expression syntax for finding php function name:

For example:

public function _c_Def()
{

}

and I like to get:

_c_Def

What I tried:

/function[\s
]+(\S+)[\s
]*\(/
(?:^|
)function ([^\s]+)

But every time I miss something

You can use PHP Reflection API to get all methods in the class instead of just parsing it by regexp.

$class = new ReflectionClass('Namespace\YourClassName');
$methods = $class->getMethods(ReflectionMethod::IS_PUBLIC);
